Crash on opening content browser

Hey I’m having trouble opening my content browser after a recent crash. It crashed and I’m assuming a missing matinee is what is causing the problem. Any help would be great.
Update:
It only crashes when I open content browser 1

Error code is as follows:

Hello,

I have attempted to reproduce your crash, but I haven’t been able to do so as of yet.

I have a few questions that can help narrow down the cause of this crash:

  • Can you reproduce this crash in a clean project?
  • Does this crash also occur in the 4.11 Preview?
  • Do you have any steps we can follow to reproduce the crash on your end?
  • Do you recall any changes you made to your project prior to the crash occurring?
3
  • It only affects this project file
  • I’m only running 4.10.2
  • Mostly just crashes when you open content browser 1(I just worked around it but its nice not to have a death button)
  • I think the reason for the problem was a crash during matinee saving or something(I cant recall)

Attached is the project file

I tried to shrink it to as low as I could

4

Could you please download 4.11 and see if the crash is still occurring?

In your project, what steps do I need to take to reproduce the crash? I did a few different things in your level and I didn’t see a crash occurring.

Hello,

I am marking this topic as resolved for tracking purposes, as we have not heard from you in a few days. If this issue persists, feel free to respond to this thread. For any new issues, please create a new Answerhub topic.

Have a great day

I ran into this as well. Window > Reset Layout solved the problem.

Yip, same problem. Thanks Jack, Window → Reset Layout solved it (though I lost 2 weeks of work). What I can say is that I was playing with adding jpg as materials. I am using 4.10.4

Thank you! I had the very same problem for the Unreal Tournament Editor (where you can’t change editor, hehe) Searched a while for a solution and this worked like a charm! Reset Layout did the job. Odd issue though.

I dont have an option to reset layout in UE5
